Abstract: Abstract of the Disclosure My invention relates to a microballistic printer in which I provide a collector wall normally struck by pro-jectiles rebounding from the platen of the printer with an anti-bounce surface.  The surface comprises a thin and flexible sheet spaced from the wall to absorb or dissipate the kinetic energy stored in the rebounding projectiles.    The sheet has a thickness of the order of four mils and is formed of a material having a ratio of yield strength to modulus of elasticity which is sufficiently high to prevent a permanent set in the area of impact by a projectile.

Abstract: ABSTRACT OF THE INVENTION 9-(2,6-Dihalobenzyl)adenines substantially free of the 3-isomer, useful as coccidiostats, are prepared in a number of ways.  One is by alkylating a salt of adenine with 2,6-dihalobenzyl halides in a two phase system in the presence of a phase transfer catalyst and then treating the resulting mixture of positional isomers, containing primarily the desired 9-isomer contaminated by substantial amounts of the mutagenic 3-isomer, by selectively dealkylating the 3-isomer with sulfuric acid in the presence of a carbenium ion trap to obtain the 9-isomer substantially free of the 3-isomer.         Alternatively, 9-(2,6-dihalobenzyl)adenines are directly prepared uncontaminated with positional isomers from 4,5,6-triaminopyrimidine via 7-(N-formyl-N-dihalo-benzylamino)[l,2,5]thiadiazolo[3,4-d]pyrimidine.

Abstract: Abstract of the Disclosure The present invention provides an air purifying system which both filters and neutralizes odors in the air.  A housing includes an inlet, an outlet, and an internal flow path from the inlet to the outlet.   The outlet is preferably configured to provide a conical exhaust flow path.  An impeller is located within the housing to move air through the housing along the flow path and out of the housing through the outlet.  A filter is interposed in and spans the flow path of the housing to filter particulate matter from the air passing through the housing.  An odor neutralizing chamber within the housing is partially interposed in the flow path. The chamber contains an odor neutralizing chemical which vaporizes in the presence of air.  A mechanism is provided for controlling the amount of odor neutralizing chemical vapor which enters the air flowing through the housing.

Abstract: TAI, K. L. 2 LITHOGRAPHIC PROCESS AND RESULTING ARTICLE            Abstract Lithographic fabrication of LSI's depends on inorganic resist to yield excellent edge acuity.  Systems depend upon photomigration--of, e.g., silver--into a chalcogenide or other glass layer to insolubilize irradiated regions with respect to solvent development. Regulation of silver content and control of processing conditions result in a surface concentration gradient and concomitant lateral diffusion of silver to account for enhanced acuity.

Abstract: "FREESTANDING DOLL TENT" ABSTRACT OF THE DISCLOSURE           The tent is formed with a fabric base, fabric sides and peaked or pyramidal roof all sewn together. A rigid base panel is inserted within the tent at the base thereof and stretches the base fabric to define the base shape and hold it in position.  A wire frame is sewn into the upper ends of the side panels at the junction thereof with the roof panels and defines the shape of the upper ends of the side panels and the lower ends of the roof panels.  This is a similar shape but smaller than the shape and dimensions of the base panel.  To erect the tent, a central post on a block is inserted into the peak of the roof by one end thereof and the block is centralized on the rigid floor panel thus rigidifying the structure vertically with the base panel and the wire frame stretching material in the lateral plane.

Abstract: Abstract of the Disclosure Disclosed is an improved method and apparatus for pyrolyzing waste materials and recovering useful chemical and energy rich materials therefrom.  The apparatus of the invention includes a specially designed, rotatable combustion chamber and embodies a highly novel means for withdrawing a portion of the combustion gases generated by the pyrolysis of the waste materials, mixing these gases with preheated air in carefully controlled proportions and then using the highly combustible gaseous mixture thus formed to sustain pyrolysis within the combustion chamber.  Of particular concern in this appolication is the provision of a high temperature liquid medium sealing means for effectively sealing the combustion chamber of the apparatus to prevent undesirable leakage of air into the chamber and at the same time prevent the escape of combustion gases therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE:          A process of recovering oil from an oil-contain-ing mineral by retorting the oil containing material and separating of oil in a separating stage from the retort gases obtained therefrom which contain the retorting pro-ducts.  The solid carbon contained in the retorted material after the retorting is burnt by a supply of oxygen-contain-ing gases, part of the resultant burnt hot mineral in admixture with the oil-containing mineral is charged into a retorting shaft reactor whereby the oil-containing mineral is heated and retorted.  At least a portion of the retorting is effected in a retorting shaft reactor, the mineral from the retorting reactor is charged onto a travel-ing grate, a subsequent retorting is effected in an after-retorting zone, in which inert or reducing gases are passed through the material. The gases from the retorting reactor and from the after-retorting zone are supplied to the said separating stage and oil is removed from the gases in the separating stage.  The retorted bed of material is moved on the traveling grate to a combustion zone.  The solid carbon contained in said mineral in the surface of said bed is ignited at the beginning of the combustion zone.  Oxygen-containing gases are then sucked through the bed to cause the burning zone to move through the bed, and the resultant burnt mineral is discharged from the traveling grate and part of the fired mineral is recycled to the retorting reactor.
